I know, now people will come out of the wood and say that they have that old system, and no, they can't upgrade Perl etc, never touch a running system etc yadda yadda. But what the heck do you then try to upgrade modules on said system when you didn't want to "touch the system"?
To quote possibly the smartest thing I've ever heard Donald Rumsfeld say (although he put it somewhat confusingly)
"There are known knowns. These are things we know that we know. There are known unknowns. That is to say, there are things that we know we don't know. But there are also unknown unknowns. There are things we don't know we don't know."
While you might not see why, let me tell you from the number of bug emails I've received about these sorts of issues, I _know_ there are scenarios we don't know about where this stuff is important.
I just don't know what they are :) Adam K
